RADIATOR: CORE.

"Application led Junev27,

One objectof my invention is to provide a i core with `flat spacer "or division `pla-tes hav# ing truss-like projections struck out `there- .from andhaving inclined end portionsV to eX- `l tend into the corrugations of one of the corrugated plates "between which Vthe spacer plates arelocated` for centering the vspacer plates in assembling the core. V i

A further object o fmy inventionis to have 'these projections hold the Vspacer. plates against thecorrugated plateson the sides opposite the projections soas to have `surface contact for the` transfer of heat from one plate tothe other.`l` i A still further object of my inventionis to dispose the projections edgewise infthe air passages to splitor divide the airl currents passing through the core to increase the air l turbulence and thus turn the colder air against the heated metal to effect better cooling.

` The invention consists further in the matters hereinafter described and claimed. In the drawingsi i Fiv. l is a front elevational view of a'radi- "ator having a core embodying the features of y i my invention; i i

Fig. 2 isA an enlarged fragmentary. front elevia-tional view of a detail of the core'structure to be hereinafter described; a

Fig.' 3 is a transverse sectionalview taken j l on line 3-f3`ofFigc2; j Figa .is a view of a spacer plate of my invention and looking at the same from one side' Y n Fig. 5' is a longitudinal sectional view taken `Online 5--5 `o Fig. 3 with' the outermost plates `of the water passages and spacingV strips omitted for the sake of illustration; and Fig. V6ffis an elevational viewof aV detail ofV construction to be hereinafter described.` j The radiator, kas indicated in Fig. l, has anl outer casing or Ashell l containing .ac'oreQ embodying the featuresfof my invention; `The core is of the cellular type and has upper and lower water tanks (not shown)v and a plurality of pairs of corrugatedisheet metal plates 3, 4 extending vertically between lthe tanks and so made and Aarranged'to form zigzag water passages 5, 5 alternated by air passages 6, 6, as instructures of this 'general character. The plates 3, 4 of each pair are oppositely disposed and are arranged to have their corrugations extend into each other with the vcorrugated marginal portions of the plates along their longitudinalfedgesoffset and 'interfitl-V spective plates 3, 4 at spaced intervals in the ,1925. seal No. 40,110. i

ting space apart the remaining intermediate portions `of the plates to provide the water passage between them, as shown in Fig.` 3. In practice, the plates 3, 4 of each pair-are integrally joined at one -end by makin the platesfrom a single piece of sheet metal r1 bbon stock and foldingiton litself intermediate its ends after being corrugated to bring the plates into the relation shown.

The, several pairs of plates 3, 4 are spaced apart to providethe-air passages 6, 6 by corrugated strips 7, 7 between and along the longitudinal edges of these plates, as shown. VThe corrugations of these strips 7 conform to the shape of the corrugations of the plates 3,4

y l 7o and,when made on hexagonal llnes as'shown in the drawings, give the front and rear facesi of the core a honeycomb appearance. These strips 7 are integrally connected with their relength thereof,A and are folded over on the plates in the' making thereof as in the Erick-V gpPatent No. 1,233,7 65, granted July 17, Al vertically disposed flat sheet metal spacer Vor division plate 8, made in accordancek with my invention, is placed in each air passage 6 between the plates 3, 4 forming the same. This plate 8 is narrower than the depth of the core and lies between the strips 7, .7, Vthe latterlholding the plate 8 fromV displacement fromfront to "rear ofthe'core, as shown iny Fig.3. l Q1 z Each plate 8' is provided with aplurality of truss-like projections 9, 9 preferably arranged 90 1n rows lengthwise of the plate `andon the l safe side thereof, as shown in Fig. 4.` Said Vjections 9, 9 extending into thecorrugations of'plate 4 on the side of the projections and with the inclined end portions ,'11, lllofthe projectionsinsurface contact with the in`105 clined side walls of the said corrugations,` as
